摘要目的研究辣椒素受体(TRPV1)、P物质和雌激素受体α(ER-α)在子宫腺肌病病灶中的表达,分析其与痛经的关联性,为子宫腺肌病疼痛机制的进一步研究提供依据。方法选择2017年7月到2019年2月术后病理诊断为子宫腺肌病的绝经前患者51例为子宫腺肌病组,不合并子宫腺肌病及痛经的宫颈上皮内瘤变绝经前患者14例作为子宫正常对照组。采用RT-PCR检测上述病灶中TRPV1、P物质和ER-α的mRNA表达,采用Western-bolt方法检测TRPV1和ER-α的蛋白表达,将其与痛经程度进行关联性分析。结果子宫腺肌病组TRPV1 mRNA和蛋白的表达均高于子宫正常对照组(P均<0.01)。子宫腺肌病中P物质 mRNA表达高于对照组(P<0.01)。子宫腺肌病中ER-α mRNA表达高于对照组(P<0.01),但两组中的蛋白表达无统计学差异。子宫腺肌病组TRPV1 、P物质和ER-α mRNA的表达与疼痛的VAS评分之间存在正相关性(r=0.548,P<0.01;r=0.350,P<0.01;r=0.292,P=0.049)。但TRPV1和ER-α蛋白在子宫腺肌病无-轻度痛经组和中-重度痛经组中未发现显著差异。结论子宫腺肌病中TRPV1、ER-α和P物质mRNA表达升高,与疼痛程度呈正相关性,提示这些因子可能在子宫腺肌病疼痛发生中起重要作用。
